Hengdian Kim Dae magnetic field strong magnet factory ---- how to shield powerful magnets or magnetic NdFeB magnets are particularly large magnetic buckle bag, sometimes interfere to some electronic products. In air transport electromagnetic products have certain restrictions. Now in the domestic air transport of magnetic products are prohibited in the international transport of electromagnetic products also have very strict regulations. We have a way to get these objects magnetic field does not affect or reduce the effects of it? Magnetic buckle bag manufacturers that shield it. Our common ordinary iron magnetic shielding. Higher magnetic shielding requirements requiring high magnetic permeability material, the material to meet this requirement is an iron-nickel alloy, which material has a high permeability. When the need to shield the magnetic field is strong, with only a single layer shielding materials, not reach the shielding requirements, that saturation will occur. In this case, one method is to increase the material thickness. But more efficient method is to use a combination of the shield, the shield in a shielding body to another, leaving an air gap between them. The air gap can be filled with any non-magnetic permeability material covered buttons do support models, such as aluminum. Much higher than the shielding effectiveness of a combination of shielding single shield, so the combination of weak magnetic shield can be reduced to a very low level. Hengdian Kim Dae-magnetic Factory ------ how to buy the most affordable of the magnet dimensions and tolerances a reasonable size selection: Sintered NdFeB magnet is to do the right rough material magnetic buckle package price, then Guests need to be based on the size of reprocessing. If the design is unreasonable size will produce waste materials into the body will increase accordingly. Please choose size when customers first and our business staff to communicate more, we will give you a reasonable size. 2, our products Dimension Tolerance: Normal for: plus or minus 0.05mm special package can do positive and negative magnetic buckle 0.03mm Lishui magnetic materials _ _ Kim Dae-magnetic buckle bag factory reputation by large magnetic Hengdian gold plant.
